Mom decided to start making Rodrick pick me up after school, just like he picked me up after swim practice. I guess that means she didn’t learn from that experience. But I did. So when Rodrick picked me up today, I asked him to please take it easy on the brakes. Rodrick said ok, but then he went out of his way to find every speed bump in town. When I got out of the van, I called Rodrick a big jerk, and then it got physical. Mom saw the whole thing unfold from the living room window. What does unfold mean here?
